L'extrémité femelle (96) de l'élément intérieur reçoit l'extrémité mâle (94) de l'autre élément intérieur, non pas par vissage mais par ajustement glissant, ce qui veut dire que l'extrémité mâle de l'élément intérieur est introduite par glissement dans l'extrémité femelle (96) d'un élément intérieur et forme un raccordement pouvant transmettre un couple. On peut monter ce raccord de tuyaux sur un train de tiges, en une seule étape, en n'effectuant qu'un seul raccordement. Ce raccord à deux éléments réduit le temps de forage par comparaison au temps requis avec des raccords classiques de tuyaux à deux éléments, dans lesquels à la fois les éléments intérieurs et extérieurs se raccordent par filetage, ce qui nécessite deux opérations de raccordement de tuyaux. On peut utiliser le raccord de l'invention en tant que système de tuyau et en tant que partie d'une machine de forage.

Title: Methode de controle de transmissions dans un systeme a access a base de collision
Inventor: TAKETSUGU MASANORI
IPC: H04W72/04
Filed: 1998-09-03
Granted: 2006-02-21
Abstract: Une méthode de contrôle de transmissions pouvant améliorer une diminution de débit lorsque la collision se produit lors de l'utilisation d'un système d'accès à base de collision. En réponse à un message de lien entrant DA11(I,0) d'une station radio fixe 10, un terminal 11 transmet un paquet de signaux D11(0), alors qu'un terminal 12 transmet un paquet de signaux D12(0). Lorsque les paquets de signaux entrent en collision frontale, la station radio fixe 10 ne les reçoit pas, mais transmet le message de lien entrant D12(I,0). Lorsque les terminaux 11 et 12 reçoivent le message de lien entrant, ils jugent que les paquets de signaux transmis par eux-mêmes sont entrés en collision de plein fouet et transfèrent ensuite à un état d'interruption dans lequel la transmission de temps aléatoire est maintenue. Lorsque le message lien entrant DA13(I,0) est reçu de la station radio fixe 10, le terminal 12 restauré de l'état d'interruption retransmet le paquet de signaux D12(0). Pendant ce temps, le terminal 11 passe à un état d'interruption lors de la réception du message lien entrant DA15(P,11) de la station radio fixe 10. Le terminal 11 ne transmet pas à l'origine un paquet de signaux mais retransmet le paquet de signaux D11(0), en raison de la demande de transmission de la station radio fixe.

Title: Image communication apparatus, server apparatus, and capability exchanging method
Inventor: TOYODA KIYOSHI
IPC: H04L12/58
Filed: 1999-09-09
Granted: 2007-11-13
Abstract: An Internet facsimile apparatus as a sender makes inquiry about capability, which a destination Internet facsimile apparatus possesses, to a local server in a local network. When the local server has no capability information of the destination stored, the sender makes inquiry to a DNS server higher than the local server and obtains capability information of the destination from the DNS server. Then, the sender registers the obtained capability information of the destination to a memory, which the local server or the sender has. This realizes that the sender can surely obtain capability information of the destination. Also, this makes it possible to automatically register capability information of the destination to the memory of the local server or the sender.

Title: High-capacity wdm-tdm packet switch
Inventor: BESHAI MAGED E
IPC: H04L49/111
Filed: 1999-09-27
Granted: 2008-08-12
Abstract: A self-configuring distributed packet switch which operates in wavelength division multiplexed (WDM) and time division multiplexed (TDM) modes is described. The switch comprises a distributed distributed channel switch core, the core modules being respectively connected by a plurality of channels to a plurality of high-capacity packet switch edge modules. Each core module operates independently to schedule paths between edge modules, and reconfigures the paths in response to dynamic changes in data traffic loads reported by the edge modules. Reconfiguration timing between the packet switch modules and the channel switch core modules is performed to keep reconfiguration guard time minimized. The advantage is a high-capacity, load-adaptive, self-configuring switch that can be distributed to serve a large geographical area and can be scaled to hundreds of Tera bits per second to support applications that require very high bandwidth and a guaranteed quality of service.
